Resurrecting an oldish thread here... 'cos I've come across a problem with the aero covers.
Has anyone else noticed this happening on their wheels? If you haven't noticed it yet, I suggest you take your aeros off and have a very careful inspect of your rims.
Photo shows where the problem is happening, and it's on all four wheels, the light grey mark in the rebated rim is where the surface has rubbed off . . recommend everyone check theirs, I surely can't be the only one this is happening to...
